Accurate Radon Testing in Central Ohio to Protect Your Home and Health
Radon is a naturally occurring radioactive gas that can enter homes through the soil beneath the building. Because it is colorless and odorless, the only way to know if radon is present at elevated levels is through professional testing.
Our team provides certified radon testing services in Columbus and Central Ohio, designed to accurately measure radon levels and help homeowners understand potential risks. Testing is conducted over a 48-hour period using continuous radon monitors (CRMs) and follows National Radon Proficiency Program standards. By identifying radon levels, we help you take the right steps to protect your home and the people living in it.
Advanced Testing Technology for Reliable Results
Our certified technicians use high-tech measurement devices known as continuous radon monitors (CRMs) to measure radon levels and evaluate building conditions. These advanced devices collect detailed hourly measurements, providing important diagnostic information that helps identify how radon behaves inside the home.
All monitoring equipment is continuously calibrated to ensure precise and reliable measurements. This attention to accuracy allows our team to properly characterize radon levels and determine whether mitigation may be needed.

When Should You Test for Radon?
Radon testing is recommended in several situations to ensure your home remains safe.
You should consider testing:
- When buying or selling a home
- If your home has never been tested
- After installing a radon mitigation system
- When finishing a basement or lower level
- After major structural renovations
- Every 2-5 years as part of routine home maintenance
- In the winter as radon levels can be higher in cold weather
Because radon levels can vary from home to home, even between neighboring houses, testing is the only way to know your home’s levels.

Radon Testing FAQs
What is a safe level of radon?
The United States Environmental Protection Agency recommends taking action when radon levels reach 4.0 picocuries per liter (pCi/L) or higher.
How long does a radon test take?
Most professional radon tests run for about 48 hours to capture accurate readings under normal living conditions.
Do all homes have radon?
Radon can be present in homes of any age, construction type, or location. Even neighboring homes can have very different radon levels.
What happens if my home has high radon levels?
If elevated levels are detected, our team can design and install a radon mitigation system tailored to your home that safely reduces radon concentrations.
Is radon testing required when buying or selling a home in Ohio?
Ohio does not legally require radon testing during a home sale, but the EPA strongly recommends it for every real estate transaction. Many buyers request testing during the inspection period, and Ohio sellers are required to disclose any prior radon test results.
How often should I retest my home for radon?
The EPA recommends retesting every two to five years, even if previous results were low. Always retest after installing a mitigation system, finishing a basement, completing major renovations, or making significant changes to your HVAC system.
Why is radon a concern in Columbus and Central Ohio?
Ohio has the fourth-highest average radon levels in the United States. Franklin, Delaware, and most surrounding counties fall in EPA Zone 1, the highest risk category. The natural geology of Central Ohio releases radon as uranium decays in the soil beneath homes.
